Class 81 (2). A flexible container for therapeutic liquid has a portion of its wall, adjacent to a suspension eye, adapted to be pressed inwards so as to form a base on which the container may stand. In its simplest form the container a, made of polyethylene or similar material, is of generally cylindrical shape and the lower end b is pressed inwards to provide a base c. A suspension lug f is attached to this end and an outlet d is provided at the other end, this being intended either to be cut off or pierced by a hollow needle, when required for use. In other forms a series of coaxial ribs or channels may be formed in the wall, so that the end may be turned in at a selected point, and ribs may be formed on the walls themselves to assist collapse of the container as the contents are withdrawn. In every case the lower end may be pulled out immediately before use to give additional volume into which further medicament may be introduced. A piercable cap of the same material as the container may be placed on the outlet and sealed to it by heating.

Abstract: 388,438. Aircraft framework. VICKERS (AVIATION), Ltd. and WALLIS, B. N., Byfleet Road, Weybridge, Surrey. 'Aug. 27, 1931, No. 24109. [Class 4.] Fuselages or other bodies of aircraft having longitudinal members and bracing-members, are constructed so that the axes of the bracing- members are geodetic lines in the contour of the structure, said members having a greater radial depth than width and being secured to each other where they intersect, so that the tendency of one bracing-member to bend outwards under endwise compressive forces is balanced by the tendency of the opposed bracing-member to bend inwards under endwise tensile forces. In one form, the structure includes four tubular booms, such as a, a<1>, subdivided lengthwise into bays in each of which channel sectioned bracing-members c .. c<3> are arranged. The bracing-members are connected together at their intersecting point between the booms by riveting a bent portion of each web c<4>, Fig. 4, to a plate d<1> and then riveting gusset plates d<2>, d<3> to the flanges. The other end of each bracing-member is riveted as at c<6>, Fig. 5, to one of the tubular booms, each of which is provided with an end fitting which includes a U-shaped member having parts e<1>, e<2> acting as gusset plates which are riveted to the flanges of the adjacent bracing-members. The middle e<5> of each end fitting is provided with a hole e<6> by which it is seated on an axially extending flange e<7> of a key-plate h which connects the tubular booms together as described in Specification 334,405, [Class 4, Aeronautics]. The bracing-members with their intersecting fittings and end fittings may be constructed by the method described in Specification 376,364. Stringers fare attached outside the structure for carrying a fabric covering ; similar stringers may also be provided on the inside of the structure. In a modification one bracing-member in each bay is continuous from boom to boom and the intersecting member is secured to it at its centre. Lattice-braced booms and bracing- bars may be employed and according to the Provisional Specification the construction may be simplified by employing straight bracing- members between the tubes and intersecting fittings.

IPC: B23D37/06
Filed: 1951-10-22
Abstract: 710,517. Broaching. GARRETT ENGINEERING WORKS, Ltd., R. Oct. 22, 1952 [Oct. 22, 1951], No. 24655/51. Class 83 (3) A broaching machine, particularly for torming the arms of T-slots, comprising a number of cutters 4 of progressively increasing size mounted on the links 7 of an endless chain. Two or more chains may cut slots of different sizes, each being driven by a separate motor 15 through reduction gearing and the chains may be horizontal, vertical or inclined. Five cutters 4 are secured in each cutting link 7 by wedges 14 held down by screws and the pivot pins 8 have rollers 9 which engage in notches in the sprockets 5, 6 and also between a pair of guide plates 10, 11 adjacent the work table 3. A vertical gap in both plates 10, 11 provides sideways guidance for the links. The work 1, which already has a straight-sided slot 2, is located on the work table with the sides of the slots engaging closely with the protruding part 7a of two links which are not fitted with cutters and the chain is then set in motion so that successive cutters gradually form the undercut portion of the slot. The first two links may, as shown in Fig. 2, have no protruding portion and be followed by a locating link having a protruding portion 7b. The protruding parts 7a of the cutter links engage the sides of the slots closely so that they also constitute locating links but they may alternatively be narrower than the slot, in which case the cutters keep the work correctly positioned. Where a link acts as a locating link, its leading sides are tapered so that it will enter the slot easily and the front side is bevelled so that, if it cannot enter the slot, it will push the work away. If all the links are formed as cutter links, the size of slot cut can be maintained as the cutters wear by removing the first cutter of the series and placing a cutter of maximum size in a vacant space at the end of the series. Automatic means, such as an air blast, may be provided for removing swarf. The Provisional Specification describes also a common drive for the chains.
